[Bug]: Chunk upload not working since update from 26 to 28.0.5 about server

Traefik downgrade to 10.0.7 did fix the issue.

502 response code means your webserver timed out, this looks like a setup issue 🤔

Traefik also had an issue and is fixed since

As i said in my issue, a friend of mine who uses a relatively standard way of hosting Nextcloud with nginx has the same issue and it only happens since i updated

@0verEngineer I understand, thanks for replying!
Can you confirm your friend experience the same errors? While the issue might look the same, it might be from different causes :)

@skjnldsv I am sorry, you are correct it is indeed a different issue, this is a screenshot from the error that happens on the instance of my friend:

I will check out the traefik stuff when i have some time. Thank you

[skjnldsv]

Thank you for taking the time to check 😊

Might be related to maybe readTimeout on Traefik, though it would be more likely in case of migration to v3. I've run into this and setting appropriately (or disabling) readTimeout sorted issue.
See this #37695 (comment) for example entry for Traefik to fix it, if this is indeed timeout issue - check your logs.
